Parts Resistor Diodes Transistors Transformer Capacitor Relay Switch LED Lamp

Resistors Oppose the flow of electricity Color coded= value 20 resistors in the kit

Diodes Allow electricity to flow in only one direction 3 diodes in kit

Transistors Used to switch, amplify, oscillate Kit has 4 transistors

Transformer raises or lower voltage

Capacitor Temporary store electricity filters the voltage level Also may increase current 10 Capacitors in kit. Every project uses a capacitor

Relay Switch using electromagnet to control a higher current

Control and Power Switch Control switch uses a variable resistor

LED Light Emitting Diode Give off light when electricity flows through them
